To all whom it may concern:

7 In said drawings: 1 Be it known that we, NELSON WHITE and Figure 1 isa right side view of an illus- CHARLES G. TIEFEL, citizens of the UnitedStates of America,.and residents of the city of Rochester, in the Stateof New York, new and useful Improvements in Checkwriters; and we herebydeclare the following to be a full, clear, and exact description of thesame.

While the invention is capable of applicounty of Monroe and cation to awide range of printing devices of various kinds, it is peculiarlyapplicable to machines of the kind known as check writers or checkprotectors for printing'on checks and other documents, words orcharacters representing amounts to prevent raising or. altering to makethe papers appear to have a nall intended.

any business concerns have come to use large check blanks known asvoucher checks and still others have their checks printed in sheets,each sheet containing a number of check blanks. It is desirable in usingcheckwriting and protecting machines to be able to print or emboss. theamount at any point or. such voucher checks or upon the different checksin a sheet without first tearing the checks apart. A

Attempts have been made in the past to produce machines capable ofprinting on large voucher checks or sheets of checks, but, in doingthis, the work supporting beds of the machines have simply been madelarger.

This has resulted in making the machines large and cumbersome, whereasone of the most desirable features such machines can have is to be smalland compact.

The objectof this invention is to provide means whereby small, compactmachines of the'kind mentioned may be so constructed as to permit usingthem to print at any point on even a very large sheet'of paper.

With this and incidental objects in view, the invention consists in thenovel construction and arrangement of parts, the essential elements ofwhich are set forth in appended claims and a preferred embodiment ofwhich is hereinafter described with reference to the drawingsaccompanying and forming a part of this specification.

have invented certain greater value than origitrative machine with theinvention applied thereto.

Fig. 2 is a detail with parts broken away and others in section to showfeatures of the invention.

F ig.- 3 is a longitudinal section through the illustrative machine.

Fig. 4 is a section on the line 4 4 of Fi 2 looking in the direction ofthe arrows.

tated in a general Way, the inventionprovides means whereby 'a sheet ofpaper to beprinted upon may easily be rolled up in the machine paper sothat an impression can be made by a printing couple upon any part of thesheet. The machine to which the invention is shown by the-act ofinserting the.

applied in the drawings is a very simple one and is intended only toillustrate how the invention may be applied generally to checkwritingand protecting machines. As will be more clearly apparent later on, theexact form of the anism for operating it is not essentialto thelnvention.

The illustrative machine has an outside I casing supporting andinclosing the mechanism. Rotatably mounted in this casing is a shaft-11having fastened thereto a type drum 12'upon the periphery of which arelines of type 13 for printing various legends. Fastened to the righthand end of the shaft 11 is a knob 14 by means of which the type drummay be turned to position any, one of the type lines 13 above a latenorimpression member 15. -Rigid wit the knob 14 is a dial or indicator 16which serves in connection with an index 17 to guide the operator insetting the type drum.

The impression member or platen is supported at its ends by arms 21journaled on a rod 22. Engaging the underside of the platen" 15 areballs 23 loosely supported in a cross bar 24 supported at its ends byarms 25 of a platen operating lever pivoted on a rod 26. Only one of thearms25 is shown in full inFig. 3, the other being broken 100 away, butit will be clear that there is one printing couple and mechof these armsat either side of the machine and that they branch from a common arm 27extending toward th s rear of the machine.

' Springs 28 maintain engagement between the ular y to draw the platendown to the pos1-' tion shown after a printing impression has beentaken. i

Pivoted to the rear end of the'arm 27 of the platen operating lever isone end of a link 31. The other end of the link 31 is.

pivoted to an arm 32 integral with an operating lever 33 and extendingthrough a slot 34 in the rear of the casing. The operating lever 33 ispivoted at 35 between lugs 36 on the casing. It isclear that if thelever 33 is pressed act as a toggle to depress the rear end of theplaten operating lever, thereby swinging thev bar 24 tension of springs37 to engage the platen a 15 with the positioned type line 13. It isyoke 42' carried by a removable plate 43 nor- .mally fastened to the topof the machine casing. Rotation of the type drum 12 to select ty e willcause the type to take from the ro ler 41 whatever ink they require forprinting.

In order to receive and guide the work between the printing couple, thatis, between the type drum 12 and the platen 15, the easmg may be slottedas shown at 44. The sides of the casing are provided with cir cularopenings providing a tubular clearance across the machine and the workreceiving slot 44 enters these circular openings in an approximatelytangential direction.-

. It 1s clear that, as so far described, if a sheet of paper is thrustinto the machine through t e slot 44, the tangential relation of theslot an circular openings 45 will cause the paper o roll upautomatically in said openings and that, with a reasonableamount ofcare, quite a Wide sheet might be inserted in this way and adjustedlaterally of the machine so as to be printed .on at any desired point.An indicator 46 on. the casing serves to guide the operator in placingthe paper to have the. printing come on the .proper line and a similarindicator (not 1 shown) on the front of the machine serves to indicatethe correct lateral adjustment of the pgper. A shield 47 extendingacross the mac ne is shaped to conform to the outline of the opemngs 45and serves to prevent the paper from striking the type 13 in case thepaper should happen tobuckle,

laten-15 and balls .23 and serve partic down the arm 32 and link 31 willand platen 15 upward against thev While the construction as described sofar would be satisfactory within certain limits,

means have been provided to make possible the use of larger sheets byrelieving friction 1 between the paper and the edges of the circularopenings 45 and at the same time affording a certain accommodation tothe adually increasing size of the roll of paper in case the papershould be given several turns in winding.

This means comprises a number of antifriction rollers'51 having theirperipheries extending into the circular openings 45 far enough to beengaged by the work when the work is pushed inthrough the slot 44. Therollers 51 are loosely supported on studs" 52 on circular plates 53 onthe sides of the machine; As shown in Fig. 2, the portions of the studsforming bearings for the rollers 51- are enough smaller than theopenings through the rollers to allow the rollers to have play radiallyon the studs and the heads of the studs are large enough to prevent therollers from being laterally displaced.

Inclosmg the studs ing shield or cap 54. This cap 54 has and rollers isa finishformed on it ears 55 and the roller supporting plate 53 hassimilar cars 56. two sets of cars are so positioned that when the partsare in proper relation, through the two pairs of cars will coincide andprovide a convenient means for attaching the devices to a machine, Boththe cap- 54 and the plate 53 are slotted as at 57 in alinement with slot44 's0 as to provide an entrance or clearance through which the work maybe inserted.

The addition of he rollers 51 provides a means whereby the frictionalresistance to the movement of the work is minimized and even with apaper which is not very stiff, the simple act of the slot 44 will causequite a large sheet to be rolled up automatically in the machine. If

the paper makes several turns, the rollers 51 are free to move radiallyon their support- .ing'studs 52 to compensate for the increase in sizeof the roll and thereby offset, to a certain extent, any' tendency thepaper may have to pinch and bind as it is being rolled While the form ofmechanism herein shown and described is'admirably adapted to fulfil theobjects primarily stated, it is screw holes thrusting the paper throughThe to be understood that it is not intended to confine the invention tothe one form of embodlment shown and described for it is susceptible ofembodiment in various forms, all coming within the scope of the claimswhich follow.
